I was watching a video tutorial in which the author has his Geometry Nodes looking like this (screenshot):
0.12ms tabs with the timer icons above each node.
The time shown is the execution time for each node. So this will show where the bottleneck is in a slow node tree. I did some searching but have only come across developer discussions about the implementation of this feature. I have no idea which builds it's in or how to enable it. Is it available for Material Nodes too, or only Geometry Nodes? Etc...
So how can I enable this? It seems very useful.
